"Dennis was very helpful in the designing of our retirement home. He was welcome to revisions and clarifications at a very reasonable price. I would highly recommend him to anyone seeking design of a single-family home."

"They were excellent. They quickly made a draft that only needed 3 minor adjustments. The final product was exactly what I needed. They referred me to a structural engineer for review. The whole process took half of the time that they initially estimated. I would definitely use them again."

"I've decided to do the work myself with some help from my son. The price was way more than I thought it would be and I could use some natural materials and spend less money. The representative from the company was professional and knew his product but, over $ 14,000 for a tub/shower replacement was way more than I wanted to spend."

"I had a door hung and some plastering work done.  The door install was great, the rest looks like a mess and will need to be done again/finished.

"I was really under the gun due to a prior Architectural firm not performing their duties per building plan codes. Not only were the plans incomplete but the City Plan Reviewer states(The Worst plans he’s ever seen) they will not make adjustments unless there is an additional charge for Thousands. Evaluation’s saved my clients and drew our project per code, along with Engineering in less time then they quoted. I highly recommended them, Especially Kirsten. You went above and beyond trying to coordinate this project. The staff was very professional and I will use them on all my projects. Sincerely, Frank B BCM Builders"
